(Cl. 73--423) bales or bags of wool and then extracting the cores from the boring tools. in most bales, the wool is dense enough to be bored with a small tool of the order of /2 inch in diameter. ever in the case of relatively loose wool in bags and the like it is necessary to use larger tools of the order of 2 and 1 /2 inches in diameter. In any case cores from a large number of bags or bales involve considerable bulk,

of bales or bags, to obtain such a sample quickly and easily, and generally to improve the art of sampling wool and similar materials.

According to the present invention the apparatus com- Preferably the aforesaid side has a plurality of apertures with one of the boring tools in each aperture, and means ward movement of the tool.

By taking a small sample of wool or the like from each of a number of batches and compressing the samples together as aforesaid, it is possible to obtain small samples which are truly representative of the average quality of a number of bales or bags.

For the purpose of illustration a typical embodiment of the invention is shown in the accompanying drawings in which- FIG. 1 is a side view with parts broken away;

FIG. 2 is a section of line 22 of FIG. 1;

FIG. 3 is a longitudinal central section of one of the coring tools with one of the aforesaid ejectors therein;

FIG. 4 is a longitudinal section of a modified coring tool; and

FIG. 5 is a section on line 5-5 of FIG. 1.

The particular embodiment of the invention chosen for the purpose of illustration .comprises a table 1 having an opening 2 to receive a bag 3 for the samples of wool or the like. Mounted on table 1 is a compression chamber 4 having a door 6 through which the chamber may be charged with samples of material, the door being heldin closed position by means of a latch 7 hooking over a 8 on the door.

opened to charge the chamber 4 with samples of material. After the door is closed and latched the plunger 9 is advanced to compress the wool against the apertured end of the chamber.

Within the scope of the I claim:

1. A machine for extracting cores from a batch of compressible material comprising a compression chamber having an opening through which material may be introduced, means for appended claims.

2. A machine for extracting cores from a batch of compressible material comprising a compression chamber having an opening through which material may be 5 introduced, means for compressing the material against one side of the chamber, said side having an aperture, a coring tool fitting said aperture, a reciprocating head suptracted position in which said coring tool is Withdrawn through the openmg into said chamber.
